Modowners

Intro

Modowners is a way to ensure that each Go dependency has at least one team responsible for maintaining and upgrading it.

The validate-modfile drone step checks go.mod and will pass if every dependency has an owner. When adding a new dependency, add the responsible team in a line comment.

Currently validate-modfile is non-blocking, but will eventually become a blocking step. All newly added dependencies will require an assigned owner.

Example of ownership assignment

cloud.google.com/go/storage v1.30.1 // @grafana/backend-platform

Utilities

check

Validate go.mod and exit with an error if a dependency does not have an owner.

Example CLI command:

go run scripts/modowners/modowners.go check go.mod

If go.mod is valid, there will be no output.

owners

List owners of given dependency.

Example CLI command to get a list of all owners with a count of the number of dependencies they own:

go run scripts/modowners/modowners.go owners -a -c go.mod

Example output:

@grafana/grafana-release-guild 5
@grafana/grafana-bi-squad 2
@grafana/grafana-app-platform-squad 13
@grafana/observability-metrics 4
@grafana/observability-traces-and-profiling 6
@grafana/aws-datasources 2
@grafana/alerting-squad-backend 22
@grafana/plugins-platform-backend 7
@grafana/grafana-operator-experience-squad 3
@grafana/dataviz-squad 1
@grafana/backend-platform 75
@grafana/grafana-as-code 11
@grafana/identity-access-team 6
@grafana/partner-datasources 4

Example CLI command to get the owner for a specific dependency (you must use dependency@version, not dependency version):

go run scripts/modowners/modowners.go owners -d cloud.google.com/go/storage@v1.30.1 go.mod

Example output:

@grafana/backend-platform

module

List all dependencies of given owner(s).

Example CLI command to list all direct dependencies owned by Delivery and Authnz:

go run scripts/modowners/modowners.go modules -o @grafana/grafana-release-guild,@grafana/identity-access-team go.mod

Example output:

github.com/BurntSushi/toml@v1.2.1

Action items

For existing dependencies, please review and update ownership of your team’s dependencies in go.mod.

• If any assignments are incorrect, you can replace your team name with the correct team in go.mod.
• If you don’t know who the correct team is, you can reassign the dependency back to backend platform. Afterwards, open a PR and assign backend platform as reviewers.
